So after many hours of listening and i mean listening i have decided to add a tweeter to this setup with a smal cap. ( cap came with the tweeter from my book shelf speakers i mod'ed a while back ) After doing this i am more happy to hear the upper high's and a little more happy i don't know what it is but i like a little bit of brightness to my speakers. Here is a pic to show you all. Also at this time im still running them with aleph mini's.. I have 4 chanels running, it is a little bit of a waste to have a separate 15watt channel dedicated to the tweeter but it sure sound's good.

I'm sure it works. Because of the distance btw the two speakers you could try phase change of the tweeter.

The main reason for this is because they are all matched channels THEY all have closely matched part's. My bigger towers Love class a. I tried a gain clone well that lasted 20 min and then fired it back out the door.

Very nice looking amp

Hi Shawn
Thanks for your kind words.

Well the circuitry is: 1st valve 6N1P input gain/phase inverter, 2nd 6BL7GTA phase splitter, with cathode compensation caps (very small values) for these two stages.
Output stage is a classic ultralinear type with 6550 (or KT88/90) with fixed bias.
As for the chassis this one is not steel: I use aluminum most of the time.
The side panels are machined from very noble and rare hardwood: the famous "pau Brasil" (yes with "s"...) (BTW this is the name of a native tree that gave its name to our country...)
Transformers: all of them made under my project and specs.
Tube brands: russian 6N1P, 6BL7 by GE and 6550C Svetlanas.
That's it.
